Re: Differential Directory, indexing method 17 Hours Ago by noahevans This is a brilliant explanation of how Differential Directory (DiDi) indexing works — very efficient and elegant. The idea of storing only the first differing bit between keys reminds me of how we optimize systems for speed and memory, much like how some tech repair services streamline diagnostics.

Using Workbooks.Open(), open the workbook, and then display the Excel window. Reference the Excel COM object in your project. Re: How to open an Excel Document in VB.NET 6 Days Ago by JamesMichaelm I see it's been a while since you posted, but I'm curious if anyone here has tried using the Open XML SDK instead of Interop or OleDb for reading Excel files. I found it faster and doesn't require Excel to be installed, though it can be more complex for writing. Wondering how others handle big Excel files or ones with tricky formatting? Re: How to open an Excel Document in VB.NET 6 Days Ago by PitSterw I've worked on something similar and found that using Microsoft.Office.Interop.Excel lets you open the file and loop through cells easily.

If a webpage could run a program installed on another computer, the entire world wide web would be hacked into tiny pieces and cease to exist. No one would ever use the web, it would be so totally insecure. So web pages are prohibited from running programs on your computer.

Re: Differential Directory, indexing method 6 Days Ago by xrjf About DiDi DiDi (Differential Directory) was originally developed as part of my thesis project in the early 1990s. The name bears no relation to the more recent Chinese ride-sharing company. At the time, DiDi was a novel approach within its academic context, but a change in legislation unfortunately led to the closure of the school and the … Re: Differential Directory, indexing method 6 Days Ago by xrjf For example, as Donald Knuth points out in The Art of Computer Programming, the theoretical lower bound for comparison-based sorting algorithms is K × log₂(N). I developed a very simple method that matches this performance. However, DiDi goes far beyond: its performance is proportional to K × (maximum key length), regardless of the number of … Re: Differential Directory, indexing method 6 Days Ago by xrjf As an illustration, consider the theoretical lower bound for comparison-based sorting, as stated by Donald Knuth in The Art of Computer Programming: K × log₂(N). I developed a simple method that matches this limit. For example, to sort the list {2, 5, 7, 1, 4, 3, 8, 6}: Sort pairs: (2, 5) → [1] (1, 7) → [2] (3, 4) → [3] (6, 8) → [4] Merge… Re: Differential Directory, indexing method 6 Days Ago by xrjf "Just to clarify a previous mistake: the efficiency should be K × N × log₂(N), not K × log₂(N) as I initially wrote."
